In the shadows of Blackwood Manor, darkness has festered for over a century.

When paranormal investigator Silas Thorne arrives to document the legendary hauntings with his specialized camera rig "The Iris," he expects to find evidence of residual energies—not a malevolent entity actively seeking to destroy him. Meanwhile, logical-minded financial auditor Eleanor "Nora" Vance has been hired to assess the decaying estate's value, dismissing local superstitions as rural folklore.

Their initial hostility quickly transforms into a reluctant alliance when a violent supernatural manifestation traps them inside the manor during a raging storm. As the entity grows stronger, targeting their deepest fears and vulnerabilities, Silas and Nora must uncover the horrifying truth behind the Blackwood family's dark legacy—a father's occult obsessions, a mother's desperate prayers, and a fratricidal tragedy that left psychic wounds still festering within the manor's walls.

With the discovery of a cursed silver locket containing the Nightstone and a blood-stained dagger, they realize they've become entangled in an ancient evil that feeds on their growing connection. To survive, they must not only confront the rage-filled spirit of Thomas Blackwood but also their own demons and deepest fears.

Will their combined strengths—his psychic sensitivity and her analytical mind—be enough to break the manor's curse? Or will they become the next chapter in Blackwood's tragic history?
